JOIIX H. HERMANN, OF HIGHLAND, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 339,774, dated April 13, 1886.

Application filed January 5, 1886.

To all whom, it nuty concern Be it known that I, JOHN H. HERMANN, a citizen of the United States, residing at Highland, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Combined Gan Rosining and Soldering Machines, of which the following is a specification.

My invention specially relates to that class of machines for soldering the end seams of sheet-metal cans in which the cans are in erted in a holder which is supported by astandard, so as to rotate while holding a can, and is universally adjustable, so as to rotate in any angle required,for the purpose of first rotating the can in a flux or rosin box and then in a box or pot of molten solder.

The construction and operation of the machine will first be described, and then those parts and combinations which constitute my invention will be designated in the claims.

In the drawings hereto annexed, Figure 1 is a front elevation of the machine, clearly showing a can held by the holder in position ready for being soldered, and also showing a gasoline-burner under the solder-box, the rosinbox being shown,partly by full and partly by dotted lines, behind the solder-box. Fig. 2is atop plan view of the machine, showing the can held by the holder in position ready for being rosined. Fig. 3 is a top plan view of Fig. 1. Fig. 4 is a detail section of the rosinbox, showing the manner of adjusting it in position for the holder, a can being shown in position for being rosined. Fig. 5 is a detail section through the solder-box,showing its adjustable features with a can in position. Fig. 6 is a detail View of the soldering-iron with a can in position. Fig. 7 is a plan section through the soldering-iron and can on line 7 7 of Fig. 6. Fig. 8 is a front view of the disk at the end of the can-holder shaft, showing the clutch device. Fig. 9 is a section on line 9 9 of Fig. 8. Fig. 10 is arear view of Fig. 8 on line 10 10 of Fig. 1.

A is the frame of the machine, and a are its four legs or standards,all made of iron. Within the frame is placed and securely fastened a wooden bed or top, B.

C is an iron pot or box which holds the hot solder. This'box; is preferably placed atthe left front'corner of the frame A, and is bolted Serial No. 187,744. (No model.)

I or otherwise held in the same. When the solder-box is in position, as shown in the drawings, its ends and sides atthe top are flush with the top of the wooden bed B.

D is the rosin-box. This is placed preferably at the rear left corner and top of the bed B.

E is my improved adjustable rotating canholder, which is supported on a p0st,E,placed to the right of the solder-box and in line with the center of same, as shown in Figs. 2 and 3. I will first proceed to describe my improved adjustable and rotating can-holder, then the rosin-box, its adjustable features, &c., and its relation to the can-holder, and, finally, the solder-box and its adjustable soldering-iron and its relation to the can-holder. v

The post E is made hollow and is fastened :tothe top of the wooden bed at its flange 6 by means of screws, nails, or bolts. WVithin this hollow post E is placed the shank end of a lforked rod, E, which is fitted so that the fork E will turn in the hollow post.

The holder E has on its shafta loose collar or sleeve, 6, by which it is pivoted or hinged in the fork E, as shownin Fig. 1. The holder thus rotates in the sleeve, which serves as a hearing, as well as permitting the holder to slide up and down in it, as indicated by dotted lines in Fig. 1, for the purpose of adapting it to long and short cans, as will hereinafter be fully described.

F is a crank or hand wheel keyed to theupper end of the holder-shaft, and by which the holder is turned or rotated.

e and e are collars or rims on the shaft, which limit the sliding movement of the holder in the collar or sleeve. The fork E in which the collar or sleeve is pivoted, permits the lower or long arm of the holder to be raised and lowered as a lever-arm, and the object of allowing the fork to turn in the hollow post is to permit the holder to swing around horizontally to any point of the circle around the post as its center for various purposes, as will be described farther on. To the lower end of the holder opposite to the hand-wheel F is provided my improved clutch device, which is constructed as follows:

G is a disk or circular plate, riveted or otherwise secured at its center to the lower end of .theholder-shaft. Through this disk are cut or cast two slots, g and g, directly opposite each other, running radially, beginning near the center of the disk and extending .toward its periphery. Vvithin these slots 9 and g are placed my two clutch-pieces, H and H, respectively, which form my adjustable clutch device for gripping cans of different diameters. One of the clutch-pieces, H, is first adjusted on the face of the disk to the size of the can to be clutched, and is held firmly and rigidly in the required position by means of a bolt, -h,which passes through the slot g,"and a nut, h, of the bolt at the other side of the disk. The opposite clutch-piece, H, is made movable on the disk and in its slot and is firmly held to a plate, h upon which it isadjusted to the size of the can by a bolt, h gwhich passes through the slot '9 of the disk, and-a slot,-h, of the plate k and a nut, h of the bolt h at the back. This plate h is placed at the back of the disk over the slot so that its slot h" is in line with and parallel to the slot of the disk.

, To the end of the plate h nearest the center of the disk is provided a lug, h,which extends into the slot of the disk, and moves in same, for guiding the movement of the plate, 860. Into this lug h, which is hollow, is inserted the short arm of a spring-lever, I, which is ful-- crumed'in a lug, i, cast on the holder-shaft, the other or long end of which lever I is provided with a spring, 1', riveted on its inner side and acting against the holder-shaft, as clearly shown in Figs. 1 and 3.

To allow the clutch-piece H to move freely in the slot 9 of the disk after it is firmly adjusted to the back plate, h I provide .it with a lug, h which fits the slot 9', and passes through it and acts as a shoulder, against which the plate is bolted, the bolt itself passing through this guide-lug. The spring i keeps the long arm of the lever I out, and the short arm in which latter keeps the plate h and its clutch-piece H in toward the center of the disk for-clamping and holding the can.

The two clutch pieces H and H are each provided with a pair of arms, 7a, which are made adjustable on the same by means of the same bolt and nuts which secure each to the respective disk and plate, and which pass through their hub 70. (See Figs. 8, 9, and 10.) When the spring-lever I is' pressed with the long arm against the holder-shaft by the operator, who grasps his hand around both the shaft and the lever, the short arm draws the plate with the clutch-piece H away from the opposite stationary clutch-piece, H, or, in other words, the clutch device is opened to receive a cam or to release one.

The rosin-boX-D is placed as shown in Figs. 2 and 3, and is hinged in an uprightframe,D, which is adjustable to the right and left, so as to bring the rosin-box farther-to the right or left on the wooden frame B by a bolt, d, which passes through the cross piece of the frameD and slot d,cut in the wooden bed, and a nut, (1 below, as clearly shown in Fig. 4. The frame D also turns on the. said bolt,

so as to bring the rosin-box in line with the hollow post on which the can-holder turns and swings.

The rosin-box is preferably made of the shape shown in Fig. 1, its upper end being open for receiving the rosin, and'a segmental circular opening at the front near the bottom directly above my improved rosin-distributer D which latter Imake of leather, rubber, or

other yielding material, and of a segmental shape reverse to the segmental opening d, so that a can held in the holder will rest with its edge and bottom in same as its bearing in which it rotates when theholder is turned. a

D is a scoop forming part of the box below for guiding the can into the position for beingv tom of the can. The can while rotating in the rosin-distributer causes the resin from the segmental opening to drop betweem-it and i the distributer, which latter distributes the rosin evenly around the edges of the can and bottom while the can rot-ates. r

The rosin-distributer may be made semicircular instead of segmental,if desired to en circle more of thee-an, and is cut from heavy sheet-rubber or lcather,preferably. The rosin-box itself is made of wood, and its front face is covered with'sheet or plate steel (2, (see Fig.

4.) for the purpose of preventing the edges of lithe cans from cutting into the wood. An ;opening, b, is cut in the wooden bed B, for

the solder-box O. This opening, asshownin Figs. 2 and 3, should be sufficiently large to leave space enough between it and the solderbox to prevent the wooden bed from catching,

fire from the burner G under the box. The

der-box, and may be a gasoline, gas, or other burner.

1 10' burner 0' serves to melt the solder in the solc are lugs cast at the top of the two sidesof the solder-box, and within these lugs is hinged a frame, 0, to which is secured .my improved soldering-iron O, which is of the shape clearly;

shown in Fig. 2. The hinged frameC' is of the H shape, the two arms of which serve as guides and supports for the soldering-iron, also clearly seen in the same figure. The

lower end of the soldering-iron is-provided Y with two segmental lugsor solder-spreaders, i c and 0, which receive the end of the can and.

bottom (see Fig. 6) and partly encircle same on each side, leaving part of same free below, so as to dip into the solder, which letter should about touch the segmental spreaders c and e", as clearly shown in Fig. 5. These segmental solder-spreaders have their-spreading-edge. a beveled inwardly to correspond to the outward bevel 0, formed at the joint between the bottom of the can and the end of .the can itself, so. that a can when in position between the spreaders is held as shown in Figs. 6 and 7, the beveled edge of the can-bottom extending in behind the front face of the segments, as clearly shown by dotted lines in Fig. 6, the outer edge of said spreaders serving to scrape the can clean from all solder adhering to its sides by coming flush against the sides of the can itself. (See Fig. 7.) Further, the soldering-iron O is provided with a semicircular or segmental notch, f, at the bottom between thetwosolder-spreaders,the edge of which said notch fserving toscrape the surplus solder from the bottom of the can as it rotates.

The rosin-spreader of the rosin-box should have its spreading-edge similarly shaped as the spreading-edge of the solder-spreaders solderingiron is raised or lowered.

just described, for the purpose of removing the surplus rosin from the side of the can.

The segmental 0r semicircular opening in the front of the rosin-box, directly above the rosin distributer or spreader, removes the surplus rosin from the bottom of the can as it rotates.

In order to make the soldering-iron with its spreaders adjustable to the height or amount of solder within the box, and so that the edge of the can will dip into the hot solder, as shown in Fig. 5, a rod, 0 is secured to the upper end of the plate or soldering-iron C by riveting or otherwise. The opposite or upper end of the rod 0 passes through a hole in the upper cross-piece of the hinged frame 0-, and a thumb-nut, c, at the top screws on the threaded end of said rod, and holds same with the soldering'iron as required. By turning the thumb-nut to the right or left the The hinged frame (3 permits the soldering-iron to tilt to the angle required for receiving the end of the can when held in the holder, so that the bottom of the can will rest flush against the face of the soldering-iron, and the segmental solder-spreaders will properly engage the edge to be soldered, as shown in Figs. 2, 5, 6, and '7.

When a change is made from one size of cans to another, it is necessary to change the solderingdron for a larger or smaller one to correspond by removing the thumb-nut at the end of the rod 0'.

The difference in the soldering-irons for different-sized cans will only exist in the solder-spreaders,which will be of di fferentradii at the spreading-edges 0 the soldering-irons C proper being of uniform size and shape, so as to fit the hinged frame 0 alike. A change, however, of the rosin-box is not always necessary, unless the size of cans to be received by it are too large to be admitted within the rosin-distributer, which will serve its purpose for several different sizes of cans.

The clutch device of the rotating can-holder will adapt itself to several differentsized cans and is but required to be adjusted by setting the clutch-pieces H and H nearer together or farther apart, as before described.

The soldering-iron O and its solder=spread ers may be made of tempered steel, so as to better withstand the constant wear to which they are subjected when many cans are soldered.

Having now fully described the construction of my newly-invented can rosining and soldering machine, the operation of same is as follows: The clutch device of the rotating can-holder is first adjusted to the diameter of the cans to be rosined and soldered. The holder is now placed in position with its forked shank inserted into the hollow post. The holder E being universally adjustable in any position, as already described, is brought with its clutch device around for receiving a can. The operator pressing the long arm of the spring-lever I toward the holdershaft opens the clutch device and inserts a can, which is immediately gripped firmly between the arms of the two clutch-pieces upon releasing the spring-lever I. The rosin-box is now adjusted with its frame D, by means of the bolt d and nut diwithin the slot d of the bed B and the frame turned on the bolt (1, so as to bring the rosin box in line with the hollow post and at the proper distance to properly receive the can when held by the holder E, as shown in Figs. 2 and 4. The soldering- 1ron is next adjusted on the frame 0" to the level of the hot solder contained in the solder pot or box, and so as to properly receive a can between its two segmental solder-Spreaders, c and c", and so that the lower edge of the can will dip into the hot solder, as clearly shown in Figs. 3, and 5. The hinged frame 0 is set so that the can when held by the holder: shaft E into the hot solder, asjust described, will come with its bottom flush against the soldering-iron O, as shown in same figures. The rosin-box now being supplied with powdered rosin, the operator takes hold of the canholder shaft E with his left hand and the hand-wheel Fwith his right hand, swings the holder around in line with the rosinbox and lowers it wit-h the can into the rosinbox until the can rests within the rosin-distributer, the hinged box adjusting itself antomatically with its front face flush against the bottom of the can, through the weight of the can-holder over-balancing the box at the front and-tilting it forward. A few turns are now given to the can by turning the handwheel F, and the rosin is distributed around thejoint, the surplus rosin removed from the can and bottom, as before described, and the can is ready for the soldering process. The operator now lifts the holder with the can up out of the rosin-box, bringsit around and forward in line with the solder pot or box and lowers it down with the can, so that the latter fits and rests between the two solder distributers or spreader-s c and c", as shown in Figs. 1, 3, 5, and 6, and the bottom of the can is flush against the soldering-iron 0 A few turns given the can again by the hand-wheel F, the solder is taken up by the end of the can as it dips into it and is distributed around the joint evenly by the solder-Spreaders and the surplus rosin removed from the can and its bottom, thus finishing the can, ready for re moval. The holder is again raised with the can, the clutch is opened to release the can, which is now removed and another can placed in its stead between the clutch-pieces, and the operation is repeated.-

What I claim is 1. The combination and arrangement,with a universally-adjustable rotating can-holder, of a rosin-box and solder pot or box, the rosinbox beingadjustable within a frame, so as to receive the can when held by the rotating holder, and the solder pot orbox having an adjustable soldering-iron Within a hinged frame for receiving the can of the holder, substantially as herein shown and described, and for their respective purposes set forth.
